Answer 1

Да формула подходит решай по этой форрмуле

Answer 2

Calculating the Resistance of a Wire in the Form of a Ring

To calculate the resistance of a wire that is formed into a ring, you can use the formula R = (L * r) / S, where: - R represents the resistance of the wire, - L represents the length of the wire, - r represents the resistivity of the wire material, and - S represents the cross-sectional area of the wire.

Please note that the formula you provided, R = (L * r) / S, is correct for calculating the resistance of a wire in the form of a ring.
